5 Written questions

5 Matching questions

  1. what kind of wave is sound
  2. in phase waves
  3. units of density
  4. units of pressure
  5. if one of the acoustic variables of pressure, density, and distance has a rhythmic oscillation then
  1. a sound is a mechanical longitudinal wave that moves by compression and rarefaction--particles in the medium vibrate back and forth from a fixed position
  2. b a pair of waves are considered in phase when their peaks (maximum values) and troughs (minimum values) occur at the same time and in the same location
  3. c pascals (Pa)
  4. d that wave is a sound wave
  5. e kg/cm cubed

5 Multiple choice questions

  1. the effects of the medium upon the sound wave (compression and rarefication)
  2. the resultant wave is smaller (of lesser amplitude) than either one of its components
  3. straight or longitudinal
  4. sound must travel through a medium, it cannot travel through a vacuum
  5. when the frequencies of the waves differ, both constructive and destructive interference occur

5 True/False questions

  1. what are some different types of wavessound, light, magnetic, and heat

          

  2. how does ultrasound workall waves carry energy

          

  3. what do waves doa pair of waves are considered in phase when their peaks (maximum values) and troughs (minimum values) occur at the same time and in the same location

          

  4. how are sound waves identifiedoscillations in acoustic variables

          

  5. if something other than pressure, density, or distance has a rhythmic oscillation thenthe wave is not a sound wave
